Stereo sound controller IC

BA3853BFS

The BA3853BFS is a dual-channel electronic volume controller built around a low-noise, low-distortion VCA. It is suited

for car-audio applications, and has performance that rivals mechanical-type volume controllers.

In addition to volume control, the IC includes all functions required for controlling sound quality, to allow more compact

designs with far fewer components.

FApplications

Car audio systems

FFeatures

1) Provides electronic control for volume, balance, fad-

er, tone (bass and treble), and loudness.

2) The volume control circuit is a low-distortion, low-

noise VCA circuit that uses DC voltage for control.

The IC uses an internally-generated, temperature-

compensated reference voltage and is capable of

dual-channel control with the addition of a single po-

tentiometer.

3) Available in an SSOP-24 package that is ideal for

compact designs.

FAbsolute maximum ratings (Ta = 25_C)
